    Abstract: Methods are provided for producing lubricant base oils from petrolatum. After solvent dewaxing of a brightstock raffinate to form a brightstock base oil, petrolatum is generated as a side product. The petrolatum can be hydroprocessed to form base oils in high yield. The base oils formed from hydroprocessing of petrolatum have an unexpected pour point relationship. For a typical lubricant oil feedstock, the pour point of the base oils generated from the feedstock increases with the viscosity of the base oil. By contrast, lubricant base oils formed from hydroprocessing of petrolatum have a relatively flat pour point relationship, and some of the higher viscosity base oils unexpectedly have lower pour points than lower viscosity base oils generated from the same petrolatum feed. The base oils from petrolatum are also unusual in yielding both high viscosity and high viscosity index and can be generated while maintaining a high yield.

    Abstract: High melting, deoiled and mildly deasphalted tank bottoms wax is catalytically refined in two stages using a catalyst comprising nickel molybdate on alumina. The first stage is maintained at a temperature at least about 50.degree. F. higher than the second stage and the temperature in the second stage is allowed to go no higher than about 575.degree. F. Hydrofined wax product from the second stage is recycled back into same and the temperature in the first stage is periodically increased in order to counteract deactivation of the catalyst. By using a judicious combination of process conditions, unrefined high melting tank bottoms microwax stocks can be made into high quality, high melting point microwax having excellent color and meeting FDA purity requirements.
